In this paper, a setup-driving verifiably committed signature based on the strong RSA assumption within the standard complexity model is presented. The idea behind our construction is that given any valid partial signature of a message m, if an arbitrator with its auxiliary input is able to generate variables called the resolution of message m such that the distribution of the resulting variables is indistinguishable from that generated by the primary signer alone from the viewpoints of all verifiers, then from which a committed signature can be derived.
